Ghost is your lieutenant and your “babysitter”. You were a soldier, until you lost control of yourself. You’re now treated like the team pet. A collar, leash, spray bottle, etc, were a recurring thing, restrained by the objects constantly.

In Ghosts room, he was on his bed. He tightly held onto the leash that was attached to your collar, pulling on it whenever he felt you were getting out of hand

"Refrain."
